基于单片机的智能蓝牙寻物系统的设计(附程序清单,电路原理图,实物图)(任务书,开题报告,论文10000字)
摘要
如今社会的发展速度十分迅速，同时也加快了人们的生活步伐，越来越多的人由于粗心或者太过于繁忙，存在丢三落四的情况。而一些重要物品的丢失或者一时找不到，会对人们造成很大的困扰和不便，甚至还会造成严重的财产损失等等。因此，以51单片机为控制器的智能蓝牙寻物系统应运而生。
本文首先对蓝牙寻物系统的产生背景、发展前景、以及新技术使用现状进行了综述，并且给出了设计中采取的方案，详细阐述了各个模块的方案选择。此次设计的这个寻物系统分为两部分，分别是子机和主机，主机部分即为手机部分，子机为寻物器部分，由单片机、蓝牙模块、声光报警模块、升压模块和电源模块等部分组成的，首先打开主机上的手机蓝牙功能对周围的蓝牙设备进行搜索，搜索到子机的蓝牙后进行配对，配对完成后，子机端的单片机通过串行端口向蓝牙模块发送数据，主机端的手机蓝牙接收数据。当主机端与子机端的距离超过一定范围时，主机端手机会立即发出警报声，提示使用者，立即回头寻找查看。蓝牙寻物器的优点有许多，比如拥有很高的可靠性，非常稳定，抗干扰，使用方便，性价比高等特点。本文对各个软硬件组成模块分别做了细致分析，最后总结了软硬件设计、调试、组合实物过程中遇到的问题和解决方法。

Design of Intelligent Bluetooth Object-Finding SystemBased on MCU
ABSTRACT
Nowadays, with the rapid development of science and technology, social science and technology are progressing, and economic development leads to the improvement of people's living standards, but busy work also accelerates people's pace of life. These reasons make people have a lot of opportunities to go out, such as travel, and so on. Because of carelessness or too haste.Many people are in such a hurry that they leave things behind. And some important items lost or can not be found for a while, will cause great trouble and inconvenience to people, and even cause serious property losses and so on. Therefore, 51 MCU as the controller of the intelligent Bluetooth object - finding system came into being.
In this paper, we introduce the Bluetooth object finding system from many aspects, such as its background ,development potential, and the current situation of application. This system is composed of STC89C52RC MCU, Bluetooth module, audible and visual alarm module, boost module and power module. The host is the mobile phone part, and the computer is the searcher part. Initially, the Bluetooth function of the mobile phone on the host should be turned on to search for the peripheral Bluetooth devices. After searching for the Bluetooth of the child unit, the matching is completed. After the matching is completed, the MCU of the child unit transmits data to the Bluetooth module through the serial port.The tooth module sends data and Bluetooth receives data in real time. When the distance between the mobile phone and the sub-machine exceeds a certain distance, the mobile phone sends out an alarm, prompts the holder to immediately look for the view. Bluetooth object finder has many advantages, such as high reliability, very stable, anti-jamming, easy to use and high cost-effective. This paper makes a detailed analysis of each hardware and software components, and finally summarizes the problems and solutions encountered in the process of hardware and software design, debugging and combination of physical objects.
